YAY! I finally managed to track down a DVD containing this short movie - it’s on a compilation called Short6, which is apparently only available in Japan.
It cost me a fortune and four of the other titles on the thing are shite (the other good one being the Periwig Maker, featuring the voice of Kenneth Branagh).
But YAY! - it arrived this morning and I have watched it over and over and over again - my kids love it too.
Anybody else seen it and wish to comment? Or suggest other quirky short films I might like?
